Application of the reaction of organometallic reagents with dialkylaminohalophosphines has provided a practical synthesis for aromatic diphosphorus compounds. The syntheses of the first primary and secondary aromatic diphosphines as well as the derivatives, P, P, P', P'- tetrakis (dimethylamino)-p-phenylenediphosphine, P, P, P', P'-tetrachloro-p- phenylenediphos-phine, and pphenylenebis (methy1phosphinic acid), are reported.
